The manual SRM is a new concept in a well established product. It features a Slow Retracting Mechanism (SRM) that permits the screen to retract slowly back into its casing without being assisted by the presenter. Traditional manual projection screens have a spring-loaded that will retract the projection surface so quickly that the force of its return may actually knock the entire unit off of its installation if not properly secured.

This risk is eliminated with the added SRM safety feature. Additional features include its auto-locking mechanism for variable height settings, black masking borders, MaxWhite (1.1 gain matte white material) with wide diffusion uniformity, lanyard for convenient operation and a versatile end cap design that accomodates both wall and ceiling installations.

Manual SRM screen sizes are available from 215cm to 305cm with your choice of 1:1 and 4:3 NTSC aspect ratios.
